On the Remote Control page, my computer's TeamViewer ID shows and there is a dash "-" in the password space. I cannot change the pw with the random pw function or by typing.
Thank you for contacting us on TeamViewer Community!
Can you kindly check on TeamViewer Client about Password settings please?
The path is TeamViewer -> Gear Wheel ⚙ on the top right corner -> Security -> Random Password - Password Strength -> change it to the suitable strength option.
Hope it would solve the mystery on your side!
